Per Sjöberg

Per Sjöberg is a Senior Lecturer/Associate Professor in Analytical Chemistry at the Department of Chemistry - BMC, Uppsala University. His research focuses on the development and application of advanced analytical techniques, particularly in the areas of mass spectrometry and chromatography for environmental analysis.

His main research interests include:

• Environmental analysis of phosphorus compounds and dissolved organic matter
• Development of novel mass spectrometry techniques, particularly electrospray ionization
• Chromatographic separation methods for complex environmental samples
• Electrochemistry coupled with mass spectrometry
• Phosphorus speciation in aquatic environments

Professor Sjöberg's recent publications demonstrate a strong focus on environmental chemistry, with particular emphasis on phosphorus cycling in aquatic systems and the characterization of dissolved organic matter. His work combines fundamental method development with practical environmental applications, contributing significantly to our understanding of biogeochemical processes. His research spans from the molecular characterization of complex organic matter to ecosystem-level nutrient cycling studies.

His scientific contributions include:

• Development of methods for analyzing inositol phosphates in environmental samples
• Studies on the isomeric complexity of dissolved organic matter
• Applications of advanced mass spectrometry for environmental analysis
• Investigation of phosphorus speciation in the Baltic Sea

Sjöberg has been actively collaborating with researchers across disciplines, including environmental scientists, microbiologists, and animal nutrition specialists. His work has implications for understanding nutrient cycling in aquatic ecosystems, addressing eutrophication issues, and developing sustainable analytical methodologies for environmental monitoring.
